Diode lasers are available fromthe red (the 600 nm region) all the way out to the far infrared (20000 nm). The materials used vary with wavelength: aluminum, gallium and phosphorus in the red through indium and arsenic in the near IR to lead salts in the far IR. I have personally seen the output from one at 805 nm- it put out 10 milliwatt which was just visible when it hit a white card at 1 inch in a dark room.
